18 Cu Ft Envirotronics Temperature/Humidity Test Chamber - EH18 Series - High-Performance Cascade

2003 Envirotronics EH18-2-5-WC Environmental Test Chamber

18 Cu. Ft. | -54°C to +71°C | High-Performance Cascade Cooling | S/N 06035903

Available for immediate acquisition is this Envirotronics EH18-2-5-WC, a high-capacity humidity and temperature test chamber. This unit features a heavy-duty 5HP cascade refrigeration system, engineered for the rapid thermal pulldowns required by aerospace, automotive, and electronic component testing standards.

Designed for facility integration, the water-cooled configuration ensures quiet operation and keeps heat rejection out of your lab, making it ideal for multi-chamber environments.

Key Features

• Industrial Build Quality: Features a fully welded, polished stainless steel interior with high-density thermal insulation for superior temperature uniformity.
• Cascade Performance: The dual 5HP refrigeration setup provides significant cooling "overhead," ensuring stable control even with high-wattage heat loads from the product under test.
• Facility Friendly: Unlike air-cooled units that dump heat into the room, this water-cooled model uses a facility water loop to maintain a cool, quiet lab environment.
• Proven Reliability: With 71,900 logged hours, this "heavy iron" chamber has a documented history of consistent performance and is built with standard components for easy long-term maintenance.
• Access & Viewing: Includes a large heated viewing window, interior lighting, and a standard 4" access port for cables and sensors.

Dealer Notes:

This Envirotronics EH18 (S/N 06035903) has been well-maintained and includes its original spec sheets and controller manuals. At 18 cubic feet, it offers a massive testing envelope at a fraction of the $65,000+ replacement cost for a modern Weiss Technik equivalent.
